Would you still consider a sound adaption on this engine? I came across the Williams TBII kit (pretty neat) when I was deciding on the AB set...sound like smoke (although not for this engine) seems like it would enrichen the experience.
Thanks again guys!

The TBII would give you horn & bell sounds. I think it plays a recorded grade crossing sequence of two long, one short, and one long horn blasts - so you wouldn't be able to do your own thing with the horn button, but that is a low cost way to go.
BTW, it seems that you're getting a lot of advice to go with the MTH DCS control system - which is fine, a lot of people use it. Just so you know, Lionel has their TMCC/Legacy system too - and a lot of people use that. Both systems have their passionate fans and sometimes on this Forum there will be some big arguments about whose train is better. It reminds me of the American Flyer/Lionel wars that kids had back in the 50's. Personally, I prefer the Lionel system. There are still a lot of people that prefer to run in the conventional mode, without any digital control system. They have a point, less things to go wrong and simple hookup. Whatever floats your boat, the point is to have fun.
